The Boshin War was a civil war in Japan, fought from 1868 to 1869 between Tokugawa bakufu and pro-imperial forces. An alliance of southern samurai (domains of Choshu and Satsuma) secured control of the imperial court. The house of Tokugawa launched a military campaign to seize the emperor's court at Kyoto, but defeated in the Battle of Toba-Fushimi. Troops loyal to the bakufu tried to regroup at Osaka Castle.
